# - These filters not modified, as their purpose is for special review
#   not dependent on context or focus:
#   - report.all.filter
#   - report.completed.filter status:completed
# - What is this -FILTER about in my filters?
#   - In each filter, we negate a non-existent virtual tag -FILTER that
#     doesn't change what the filter matches but does add a recognizable
#     marker. This is used later to substitute the filter with a new one when
#     it changes.
#   - CAUTION: do not add any additional (i.e. non-context, non-focus) material
#     after -FILTER in the report filter variables or else it will be lost next
#     time the context or focus is changed.
